Technologies powering digital transformation

The Network is changing ….

Digitale Geschäftsmodelle & -architekturen basieren auf Software-defined-Network (SDN)

Automatisierung und Virtualisierung breiten sich in alle Netzwerke aus

Netzwerk Device-Management entwickelt sich von CLI zu API

Programmieren wird integraler Bestandteil für Systemadministration

Wireless-Technologien verdrängen kabelgebundene Netzwerke

Wachsende Sicherheitbedrohungen verlangen neue Fähigkeiten

Neue Anforderungen an die IT-Infrastruktur und die neuen Technologien fordern erweiterte Kompetenzen (advanced skillset)

Example Business Intent:

“Disable all network access ports after 30 days of inactivity”

Automation – Save time, less mistakes

Manual (for EVERY switch) Automated (run the code once)

1. ssh to every switch2. Check the interfaces stats3. Identify which interface is affected4. conf t

int Gi1/2/3 ! Or was it Gi1/2/4 ?shut

end

# … some core removed for simplicity …

for switch in my_network:

for interface in switch:

if interface.is_up() and interface.last_change() > thirty_days:

interface.shutdown()

interface.set_description("Interface disabled per Policy")


Example Business Intent:

CyberOps request - “Where is 10.1.2.3 in our network?”

Troubleshooting – Check a single source

Manual (repeat for many locations) Automated (code checks for you)

1. ssh to multiple routers and switches2. run multiple times3. sh ip ro4. sh ip arp5. sh mac-address table6. sh cdp ne7. Look at the text outputs and

search for 10.1.2.3, …8. Put it all together

import requests

ip = input("What IP you want to find? ") # 10.1.2.3

a = {"X-Auth-Token": “…”}

r = requests.get("http://APIC-EM/api/v1/host?hostIp="+ip, headers=a).json()

print(r)
